Image is too dark. PSP has been overexposed or image
processing parameters are incorrect.
Adjust brightness or other image
processing functions within software. If this does
not resolve the problem, retake image with proper
(lower) exposure after erasing the PSP.
Image is too light. PSP has been underexposed or image
processing parameters are incorrect.
Adjust brightness or other image
processing functions within software. If this does
not resolve the problem, retake image with proper
(higher) exposure after erasing the PSP.
Image appears skewed on
monitor
PSP was fed skewed When inserting PSP into inlet feed slot, be sure
align PSP, and then push down uniformly as
instructed in the manual. Use Plate Protector

Image contains ghost images
or shadows.
PSP was not completely erased.
PSP was exposed with the back of the
PSP facing the tubehead. Image will be
reversed (mirrored).
PSP has been stored in cassette for too
long.
Partial erasure of the image due to
exposure to light during handling of the
PSP.
Check Eraser function.
Increase the amount of time that is used to erase
PSPs. Alternatively, increase the intensity of the
light source.
To test if a PSP is completely erased, scan it after
erasing. If no image is obtained, your procedure
was effective.
If using an ALLPRO ScanX 14 Eraser, check proper
functioning of the Eraser.
Refer to the ALLPRO ScanX Eraser Operator’s
Manual.
Ensure the PSPs are inserted properly into the
cassette, and the proper orientation to the
X-ray source is maintained.
Do not store PSPs in cassettes for more than 24
hours. Natural radiation results in noise in the
image.
Do not leave exposed PSPs in well lit areas.
Even when in the Plate Protector, some light may
enter periphery and partially erase the PSP.
Transfer PSPs from their protective barriers to the
ScanX as soon as possible, within one hour of
exposure.
Image shows artifacts The PSP surface is not clean and has dirt,
stains or scratches on it
Clean the PSP.
Do not use if the PSP is scratched or stained.
